Cylinder Heads need to be resilient. They have to withstand immense pressures and very high temperatures while maintaining their shape in order to seal the cylinder block through the head gasket. They are key to controlling the flow of air in and out of the cylinders and the delivery of fuel.
The cylinder head also contains the fuel injectors and valves and contains more moving parts than any other part of the engine.
Largely unnoticed, the cylinder head plays a key role in your engine. It's a tangible item that sits on top of your device and covers its operation. It is sealed with the head gasket.
Inside the cylinder head are a series of channels called ports or tracks through which the air mixture reaches the intake valves. Other clues in the cylinder head are the path taken by the exhaust gases as they leave the main engine block.
For all water-cooled engines, this applies to all Perkins engines, the cylinder head also contains ducts and ducts. These allow the coolant, which consists of water and antifreeze, to flow and transfer excess heat from the main body of the engine to the radiator, preventing the risk of overheating and damage. Unsurprisingly, the cylinder head is exposed to extreme temperatures that it must withstand.
